Chitsimikizo cha wopanga machubu enieni a boiler
Chitoliro chachitsulo chosasunthika chokwera kwambiri komanso chitoliro cha boiler chothamanga kwambiri ndi mtundu wa chitoliro cha boiler, chomwe chili mgulu la chitoliro chopanda chitsulo. Njira yopangira ndi yofanana ndi chitoliro chosasunthika, koma pali zofunikira zokhwima pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo. Machubu a boiler othamanga nthawi zambiri amagwiritsidwa ntchito pansi pa kutentha kwambiri komanso kupanikizika kwambiri. Machubu opopera oponderezedwa kwambiri amagwiritsidwa ntchito makamaka popanga machubu otenthetsera, machubu otenthetsera, machubu a mpweya, machubu akulu a nthunzi, ndi zina zambiri zama boiler othamanga kwambiri komanso othamanga kwambiri.
Machubu otenthetsera otsika komanso apakatikati gb3087-2008 ndi machubu otenthetsera kwambiri GB5310-2008 ndizitsulo zapamwamba kwambiri za carbon structural zitsulo zotentha komanso zoziziritsa (zopindika) zopanda msoko zopangira machubu otentha kwambiri, machubu amadzi otentha otsika komanso othamanga kwambiri. ma boiler okhala ndi zida zosiyanasiyana ndi machubu otentha kwambiri, machubu akulu a utsi, machubu ang'onoang'ono a utsi ndi machubu a njerwa opangira ma locomotive boilers. Chitoliro chachitsulo chosasunthika (GB / t8162-2008) ndi chitoliro chachitsulo chosasunthika pamapangidwe ambiri komanso makina.
Mafotokozedwe ndi maonekedwe abwino:GB5310-2008 machubu opanda chitsulo opangira ma boilers othamanga kwambiri, machubu akunja otentha ndi 22 ~ 530mm, ndipo makulidwe a khoma ndi 20 ~ 70mm. Chitoliro chozizira chokoka (chozizira) chimakhala ndi mainchesi akunja a 10 ~ 108mm ndi makulidwe a khoma la 2.0 ~ 13.0mm.
Chitoliro chapadera chopangidwa ndi chitsulo chosasinthika ndi dzina lambiri la chitoliro chopanda chitsulo chokhala ndi mawonekedwe ena kupatula chitoliro chozungulira. Malinga ndi mawonekedwe osiyanasiyana ndi kukula kwa chitsulo chitoliro gawo, akhoza kugawidwa mu ofanana khoma makulidwe apadera-woboola pakati zitsulo chitoliro (code D), osalingana khoma makulidwe wapadera woboola pakati zitsulo chitoliro (code BD) ndi variable awiri woboola pakati wapadera woboola pakati. Chitoliro chachitsulo chosasinthika (code BJ). Chitoliro chapadera chowoneka bwino chachitsulo chimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana omangira, zida ndi zida zamakina. Poyerekeza ndi chitoliro chozungulira, chitoliro chowoneka mwapadera nthawi zambiri chimakhala ndi mphindi yokulirapo ya inertia ndi gawo modulus, ndipo chimakhala ndi kupindika kwakukulu komanso kukana kwa torsion, komwe kumatha kuchepetsa kulemera kwake ndikusunga chitsulo.
(1) Gb3087-2008 machubu achitsulo opanda msoko a ma boiler otsika komanso apakatikati. Njira yoyezetsa mankhwala iyenera kukhala molingana ndi magawo ofunikira a gb222-84 ndi gb223 njira zowunikira mankhwala achitsulo, chitsulo ndi aloyi.
(2) GB5310-2008 machubu opanda zitsulo osasunthika a ma boilers apamwamba kwambiri. Njira yoyezetsa mankhwala iyenera kukhala molingana ndi magawo ofunikira mu gb222-84, njira zowunikira mankhwala achitsulo, chitsulo ndi aloyi ndi njira za gb223 zowunikira chitsulo, chitsulo ndi aloyi.
(3) The mankhwala zikuchokera kunja kukatentha zitsulo mipope adzawunikidwa molingana ndi mfundo zogwirizana mu mgwirizano (1) High khalidwe mpweya structural zitsulo makalasi monga 20g, 20mng ndi 25mng.
(2) Aloyi structural zitsulo makalasi: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, etc.
(3) Kuphatikiza pa kutsimikizira kapangidwe ka mankhwala ndi makina, machubu a boiler a 1Cr18Ni9 ndi 1cr18ni11nb omwe amagwiritsidwa ntchito muzitsulo za dzimbiri zosagwira kutentha adzayesedwa ndi hydrostatic test, flaring and flattening test imodzi ndi imodzi. Mipope yachitsulo iyenera kuperekedwa pakatenthedwe.
Komanso, pali zofunika zina za microstructure, kukula kwa tirigu ndi decarburization wosanjikiza wa chitoliro yomalizidwa zitsulo.
